+
+You can whitelist notifications from certain namespaces / articles by adding them into this array. Note: This targets all pages starting with the name. ALL Other notifications will be discarded, When active, the previously listed exclusion array will further limit this whitelist.

+// Actions (add, edit, modify) will be notified to Slack room from articles starting with these names
+$wgSlackIncludeNotificationsFrom = ["IT:", "Specialgroup"];
